I have categories of quilts. I have finished three this year, but they were not very big (about 54" square) and they were all machine pieced/quilted. These are "quickies".
My "real" quilts are the hand appliqued ones, usually at least queen size. Of those I finish maybe one every couple of years, I start at least two to four others a year (yep, that would account for all the project boxes stacked around LOL) and I plan/design (right up to printing designs/templates and collecting fabrics) about six a year.
I don't work anymore but teaching eats into my time significantly, and I find I am reluctant to spread out my work if I know I will have to pack it away in a few hours for a class. So I have set up a second sewing area for my work. Unfortunately it is a great area in spring/summer/autumn, but uninviting in winter, so it will be a few months yet before I find out if this will increase the quilt output significantly. I don't do much sewing in winter.
Like many others, I have far more plans than I will ever have time for, and I am racing rapidly failing eyesight. Starting new quilts for me is really being in denial - but I am OK with living in a state of denial LOL.
